DTC Advanced Diagnostics: U0131 (PGM-FI System): General Description

Courtesy of HONDA, U.S.A., INC.

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (F-CAN_H and F-CAN_L). When the powertrain control module (PCM) does not receive the signals from the electrical power steering (EPS) control unit via the F-CAN lines for a set time, the PCM detects a malfunction and stores a DTC.
